How do you predict how high a horn loads the driver ?I have made a couple of 200hz round fronthorn, and they sound great with Lowther PM2A but they have too much midrange with Coral Beta 8.
Now I know that its because of the Coral driver having a flat response vesus the Lowther which has a rising response curve.
Does the horn load up to the wavelenght that matches the diameter of the horn mouth ?
